LCP vs. Thermoplastic PI
Both LCP and thermoplastic PI are thermoplastics. There are 13 material properties with values for both materials. Properties with values for just one material (4, in this case) are not shown.
For each property being compared, the top bar is LCP and the bottom bar is thermoplastic PI.
